This invention relates to a 'clock tomobile instrument board.

In "placing a clock upon an instrument board a difficulty has arisen inthat the location of the clock movement in close proximity to the boardpositions the winding stem so closely to the board as to be diflicult ofmanipulation.

It is an object of this invention to conveniently locate the windingstem away from the instrument board.

A further object is to arrange for the use of a thin clock movement anda spaced dial the arrangement beiner intended for the lofor an aucationof the dial adJacent the instrument board whilel the clock movement withits winding stem is considerably removed from the board. A furtherobject is to et `a clock assembly of variable depth, an one which makesuse of but very few special parts lto secure the variability;l andanother advantage to be attained is the possibility of puttin any shapeor size of bezel projecting throug the instrument board on the sameclock assembly whereby the final appearance of the clock is determined.

With these and other objects in view, the invention has been embodied incertain structures as herein shown and described in the accom anyingdrawings.

In the rawing: y Figure 1 is a front elevation looking to- .i ward' theinstrument board from within the car. Figure 2 is a vertical section online 2-2 v`Figure 1. Figure 3 is a horizontal section on line 3-3 inFigure 1. Figure 4 isa section through the spindle.

Referring to the drawing, referencenumeral 1 is usedto represent theinstrument board of a car. Numeral2 shows a base member, Vin a recess 3of which is placed a comparatively thin clock movement 4. 'I2-his clockmovement is held 'in position -by screws 5. Projecting from the base isan apertured lu 6 carrymg an extended sleeve 7. Through t issleeveprojects a winding stem 8 having at its`outer and a handle 9. Differentfrom the usual. clock construction the dial 10 is spaced from the clockmovement by means of a plurality of sleeves 11. Passing through the dialand sleeves 11 and threaded into base 2 are fastening screws 12. For thepurpose of driving the hands of the clock, 13 two tubular drivingspindles 14 and 15 are made use of. YThese spindles en- To complete theclock case a cylindrical casing membery 18 is secured to the base 2.This casing member extends to a point somewhat beyond the dial where itis provided wlth an annular outwardly projecting flange 19. A plate 20,circular in shape, is depressed between its outer portion and itscentral portion, and thc central portion is cut out as at 21 to 4formwith the dial a clock face of appropriate .size and shape. It will beseen that the opening is out of the plane of the major part .of theplate and the. connecting portion is formed as.` a ledge 22 to engagethe glass '23. Cooperating with the plate 20 is a plate 24. This plate24 has its central portion cut out andis formed with a bead 25. This'bead engages the glass/.Q

around the opening, theopening correspondmg in shape and size withtheopening in plate 20. Plate 24 is ofl greater extent than the plate 2Oand its outer wall is bent over to form an annular ocket. Within thisan-' nular pocket are t e flange of the member 18 and the outer portionof the plate 20. An annular spacing member 26 may also bemade use ofbetween the flange of casing member 18 and plate20. This member 26 isrefrably a gasket to seal the assembly om ust. v f

For securing the clock case to the instrument board, clamps are made useof comrising` threaded bolts 27 and U-shaped mem# -ers 28. l One of thelarms of the U-'shaped member engages the instrument board and the otherenga'ges the turned over edge of plate 24 as will be readily understoodfrom examination of lthe drawlng.

By the mechanism described above it is possible to use a thin clockmovement in a relatively deep case. The clock movement being` at thebottom of the case and its winding stem projecting therefromconsiderably removed from the instrument board. In

so positioning the clock movement the dis-v curing the clock case on theboard is such as to obtain the desired position of the dial andcooperating therewith is the novel means for holding the clock glassinto position.

By the use of the parts, as described, assemblies of varying depths areprovided for use upon different instrument boards.

But few special parts are needed to accom- I plish this-purpose, i. e.,the casing 18, spac- 18 ing members 11, screw 12 and sleeves 14 and 15.These parts are all simple and cheap to manufacture.

The essential parts of the clock, such as the clock movement 11', dial10 and hands 13,

would be the same in each case. In this Way it would be possible to haveone model of clock manufactured in several depths, thev any shape orsize of bezel projecting throng the instrument board on the same clockas- 30 sembly. This is made possible by using a plate 24, having a bead25, the shape of which controls the final appearancelof the clock fromthe outside. It is obvious that very many different sizes and shapes ofbead 25 can be had and still the circular plate 24 will fit the sameflange 19 on the casing It will be, also, readily seen that thesefeatures make this type of construction an important improvement fromthe manufacturing standpoint.

Modifications of the specic structure shown and described above arepossible and are Within the contemplation of the inventor.

I claim:

In` combination, a clock movement having a frame, a removable coaxialcasing in extension of the frame, a dial in the end of thel casingremote from the frame, means for fixing the dial to the frame andcasing, a'

removable extension shaft connecting the movement with the dial hands,and means for securing the casing to an instrument board. p l

In testimony whereof I aflix my signature.
